A thousand-year-old tooth has provided genetic evidence that the so-called “Taíno”, the first indigenous Americans to feel the full impact of European colonisation after Columbus arrived in the New World, still have living descendants in the Caribbean today.

Direct genetic traces of the earliest Native Americans have been identified for the first time in a new study. The genetic evidence suggests that people may have entered the continent in a single migratory wave, perhaps arriving more than 20,000 years ago.

Earliest archaeological evidence of intestinal parasitic worms infecting the ancient inhabitants of Greece confirms descriptions found in writings associated with Hippocrates, the early physician and ‘father of Western medicine’.

The first study to compare ancient and living female bones shows that women from early agricultural eras had stronger arms than the rowers of Cambridge University’s famously competitive boat club. Researchers say the findings suggest a “hidden history” of gruelling manual labour performed by women that stretched across millennia.

A 2,000-year-old intact and inscribed sundial – one of only a handful known to have survived – has been recovered during the excavation of a roofed theatre in the Roman town of Interamna Lirenas, near Monte Cassino, in Italy.

The largest study to date of body sizes over millions of years finds a “pulse and stasis” pattern to hominin evolution, with surges of growth in stature and bulk occurring at different times. At one stage, our ancestors got taller around a million years before body mass caught up.
